and thus preventing rekindling of a fire in substances which have been treatedwith the compound for the purpose'ot' extinguishing 1 fire therein. v

My improved compound consists, generally,

of five ingredients, in the following approximate proportions, viz: Water, twenty-five galbe;th oroughiy dissolved, I then add the silicate of soda, stirring the mixturebriskly at 0 the same time, and. finallymix in thoroughly the red chalk,wh'en the compound is completed and-ready for use, and willinstantly extinguish fire in the most infiam mablesnbstances, even petroleum and benzoline.

35 The hand, after being immersed'in the liquid ingredients being then compound, may be placed for a short 'timeiu 1 a flame without being burned.

Being'free from acid, the compound maybe f applied by means of any utensil without injury to the san1e,-the quantity required being very much less than that required of water, the proportion being about as one of the compound Y to ,teirni' srater..

The componnd will bear any degree of cold without freezing, and may be stored for years without losing its efficiency.
